Growing number of e-readers

The number of people who own e-readers such as the Nook and the Kindle has grown to 12 percent, a survey said Monday.

The Pew Internet & American Life Project said that e-reader ownership has doubled in the past six months.

The adoption of tablet computers such as the iPad has been slower, at about 8 percent.

A small number — 3 percent — own both.

The report also found that Latinos own the most e-books at 15 percent. Homes with annual incomes of at least $75,000 also have a high rate of ownership at 17 percent. One fifth of college graduates also own e-readers.
